     The Notes will be issued pursuant to an indenture, to be dated as of July

dated as of the Closing Date (as defined in Section 2) (the "DTC Agreement"),
among the Company, the Trustee and the Depositary.

     The holders of the Notes will be entitled to the benefits of a registration
rights agreement, to be dated as of July 3, 2003 (the "Registration Rights
Agreement"), among the Company, DigitalNet Holdings, the Subsidiary Guarantor
and the Initial Purchasers, pursuant to which the Company will agree to file,
within 45 days of the Closing Date, a registration statement with the Commission
(as defined below) registering the Exchange Securities under the Securities Act
(as defined below).

     The payment of principal, premium and Liquidated Damages (as defined in the
Indenture), if any, and interest on the Notes and the Exchange Notes (as defined

unsecured basis, jointly and severally by each of (i) DigitalNet Holdings, Inc.,
a Delaware corporation and the direct parent corporation of the Company
("DigitalNet Holdings"), (ii) DigitalNet Government Solutions, LLC, a Delaware
limited liability company and a wholly owned subsidiary of the Company ("DGS" or

<Page>

terms of the Indenture, and their respective successors and assigns (together
with DigitalNet Holdings and DGS, the "Guarantors"), pursuant to their
guarantees (the "Guarantees"). The Notes and the Guarantees attached thereto are
herein collectively referred to as the "Securities"; and the Exchange Notes and
the Guarantees attached thereto are herein collectively referred to as the
"Exchange Securities".

     The Securities are being issued as part of a series of related
transactions. These concurrent transactions include the establishment of a
$50,000,000 senior credit facility (the "New Credit Facility") provided to the
Company by a syndicate of lenders led by Bank of America, N.A., the repayment of

     DigitalNet Holdings, the Company and the Subsidiary Guarantor understand
that the Initial Purchasers propose to make an offering of the Securities on the

defined below) and agree that the Initial Purchasers may resell, subject to the
conditions set forth herein, all or a portion of the Securities to purchasers
(the "Subsequent Purchasers") at any time after the date of this Agreement. The
Securities are to be offered and sold to or through the Initial Purchasers
without being registered with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Securities
Act," which term, as used herein, includes the rules and regulations of the
Commission promulgated thereunder), in reliance upon exemptions therefrom. The
terms of the Securities and the Indenture will require that investors that
acquire Securities expressly agree that Securities may only be resold or
otherwise transferred, after the date hereof, if such Securities are registered
for sale under the Securities Act or if an exemption from the registration
requirements of the Securities Act is available (including the exemptions
afforded by Rule 144A ("Rule 144A") or Regulation S ("Regulation S")
thereunder).

     The Company has prepared and delivered to each Initial Purchaser copies of
a Preliminary Offering Memorandum, dated June 17, 2003 (the "Preliminary
Offering Memorandum"), and has prepared and will deliver to each Initial
Purchaser, copies of the Offering Memorandum, dated June 27, 2003, describing
the terms of the Securities, each for use by such Initial Purchaser in
connection with its solicitation of offers to purchase the Securities. As used
herein, the "Offering Memorandum" shall mean, with respect to any date or time
referred to in this Agreement, the Company's Offering Memorandum, dated June 27,
2003, including amendments or supplements thereto, any exhibits thereto, in the
most recent form that has been prepared and delivered by the Company to the

Issuer Information (as defined in Section 3) furnished by the Company prior to
the completion of the distribution of the Securities.

of ERISA. No claim (other than routine claims for benefits) is pending with
respect to the administration or the investment of any assets of any company
plan of DigitalNet Holdings or any of its subsidiaries.

including without limitation, any notice of any program cancelation or change in
program schedule, contract reduction, modification or early termination, that
could reasonably be expected to have a material adverse effect on its ability to
recognize revenue during the year ended December 31, 2003 from approximately 30%
of its total backlog as of December 31, 2002.

     (kk) REGULATION S. Each of DigitalNet Holdings, the Company, the Subsidiary

     (b) AMENDMENTS AND SUPPLEMENTS TO THE OFFERING MEMORANDUM AND OTHER

shall occur or condition exist as a result of which it is necessary to amend or

Memorandum, as amended or supplemented, will comply with law.

     Following the consummation of the Exchange Offer or the effectiveness of an
applicable shelf registration statement and for so long as the Securities are
outstanding if, in the reasonable judgment of the Initial Purchasers, the
Initial Purchasers or any of their affiliates (as such term is defined in the
rules and regulations under the Securities Act) are required to deliver a
prospectus in connection with sales of, or market-making activities with respect
to, such securities, to periodically amend the applicable registration statement
so that the information contained therein complies with the requirements of
Section 10 of the Securities Act, to amend the applicable registration statement
or supplement the related prospectus or the documents incorporated therein when
necessary to reflect any material changes in the information provided therein so
that the registration statement and the prospectus will not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements therein, in the light of the circumstances existing
as of the date the prospectus is so delivered, not misleading and to provide the
Initial Purchasers with copies of each amendment or supplement filed and such
other documents as the Initial Purchasers may reasonably request.

suspension of the qualification or registration of (or any such exemption
relating to) the Securities for offering, sale or trading in any jurisdiction or

Subsidiary Guarantor agree that it will not and will cause its Affiliates and
subsidiaries not to make any offer or sale of securities of the Company of any

<Page>

this Agreement. Except as provided in this Section 4, Section 6, Section 8 and
Section 9 hereof, the Initial Purchasers shall pay their own expenses, including
the fees and disbursements of their counsel.

     SECTION 5. CONDITIONS OF THE OBLIGATIONS OF THE INITIAL PURCHASERS. The
obligations of the several Initial Purchasers to purchase and pay for the
Securities as provided herein on the Closing Date shall be subject to the
accuracy of the representations and warranties on the part of DigitalNet
Holdings, the Company and the Subsidiary Guarantor set forth in Section 1 hereof
as of the date hereof and as of the Closing Date as though then made and to the
timely performance by DigitalNet Holdings, the Company and the Subsidiary
Guarantor of their respective covenants and other obligations hereunder, and to
each of the following additional conditions:

     (a) ACCOUNTANTS' COMFORT LETTER. On the date hereof, the Initial Purchasers
shall have received from Ernst & Young LLP, independent public or certified
public accountants for DigitalNet Holdings, a letter dated the date hereof
addressed to the Initial Purchasers, in form and substance satisfactory to the
Initial Purchasers, confirming (i) that they are independent accountants within
the meaning of Rule 101 of the American Institute of Certified Public
Accountants (the "AICPA") Code of Professional Conduct and its interpretations
and rulings and (ii) that they have performed a review of the unaudited interim
financial information of DigitalNet Holdings for the three-month period ended
March 31, 2002 in accordance with Statement on Auditing Standards No. 100 ("SAS
100"), and the three-month period ended March 31, 2003, in accordance with SAS
100 and a review of the unaudited interim financial information of DGS for the
three-month period ended March 31, 2002 in accordance with SAS 100, and stating
in effect that:

                    (i) in their opinion the audited financial statements
            included in the Offering Memorandum and reported on by them comply
            as to form in all material respects with the accounting requirements
            of the Securities Act and the related rules and regulations adopted
            by the Commission, as if the offering had been registered under the
            Securities Act;

                    (ii) on the basis of a reading of the latest unaudited
            financial statements made available by DigitalNet Holdings and its
            subsidiaries; their limited review, in accordance with standards
            established under SAS 100, of DGS' and DigitalNet Holdings'
            unaudited interim financial information for the three-month period
            ended March 31, 2002 and in accordance with standards established
            under SAS 100, of DigitalNet Holdings' unaudited interim financial
            information for the three-month period ended March 31, 2003,
            included in the Offering Memorandum, carrying out certain specified
            procedures (but not an examination in accordance with generally
            accepted auditing standards) which would not necessarily reveal
            matters of significance with respect to the comments set forth in
            such letter; a reading of the minutes of the meetings of the
            stockholders, directors and audit and compensation committees of
            DigitalNet Holdings and its subsidiaries; and inquiries of certain
            officials of DigitalNet Holdings who have responsibility for
            financial and accounting matters of DigitalNet Holdings and its
            subsidiaries as to transactions and events subsequent to December
            31, 2002, nothing came to their attention which caused them to
            believe that:

<Page>

                         (1) any unaudited financial statements included in the
                  Offering Memorandum do not comply as to form in all material
                  respects with the accounting requirements of the Securities
                  Act, as if the offering had been registered under the
                  Securities Act; and said unaudited financial statements are
                  not in conformity with generally accepted accounting
                  principles applied on a basis substantially consistent with
                  that of the audited financial statements included in the
                  Offering Memorandum;

                         (2) with respect to the period subsequent to March 31,
                  2003, there were any changes, at a specified date not more
                  than five days prior to the date of the letter, in the
                  long-term debt or other liabilities of DigitalNet Holdings and
                  its subsidiaries or the capital stock of DigitalNet Holdings
                  or decreases in the stockholders' equity or total assets of
                  DigitalNet Holdings as compared with the amounts shown on the
                  March 31, 2003, consolidated balance sheet included in the
                  Offering Memorandum, or for the period from April 1, 2003, to
                  such specified date there were any decreases, as compared with
                  the results of DGS and its subsidiaries for the corresponding
                  period in the prior years, in revenues, income from operations
                  or net income of DigitalNet Holdings and its subsidiaries,
                  except in all instances for changes or decreases set forth in
                  such letter, in which case the letter shall be accompanied by
                  an explanation by DigitalNet Holdings as to the significance
                  thereof unless said explanation is not deemed necessary by
                  Banc of America Securities LLC;

                    (iii) they have performed certain other specified procedures
            as a result of which they determined that certain information of an
            accounting, financial or statistical nature (which is limited to
            accounting, financial or statistical information derived from the
            general accounting records of DigitalNet Holdings and its
            subsidiaries or DGS and its subsidiaries) set forth in the Offering
            Memorandum, agrees with the accounting records of DigitalNet
            Holdings and its subsidiaries or DGS and its subsidiaries, excluding
            any questions of legal interpretation; and

                    (iv) on the basis of a reading of the unaudited pro forma
            consolidated financial statements included in the Offering
            Memorandum (the "pro forma financial statements"); carrying out
            certain specified procedures; inquiries of certain officials of
            DigitalNet Holdings or the Company who have responsibility for
            financial and accounting matters; and proving the arithmetic
            accuracy of the application of the pro forma adjustments to the
            historical amounts in the pro forma financial statements, nothing
            came to their attention which caused them to believe that the pro
            forma financial statements (A) are not stated on a basis
            substantially consistent with that of the audited financial
            statements of DigitalNet Holdings included in the Offering
            Memorandum, (B) do not comply as to form in all material respects
            with the accounting requirements of Rule 11-02 of Regulation S-X, as
            if the offering had been registered under the Securities Act or (C)
            that the pro forma adjustments have not been properly applied to the
            historical amounts in the compilation of such statements. References
            to the

<Page>

            Offering Memorandum in this paragraph include any supplement thereto
            at the date of the letter.

     (b) NO MATERIAL ADVERSE CHANGE OR RATINGS AGENCY CHANGE. For the period
from and after the date of this Agreement and prior to the Closing Date:

            (i) in the judgment of the Initial Purchasers there shall not have
     occurred any material adverse change, or any development that could
     reasonably be expected to result in a material adverse change, in the
     condition, financial or otherwise, or in the earnings, business, operations
     or prospects, whether or not arising from transactions in the ordinary
     course of business, of DigitalNet Holdings and its subsidiaries, considered
     as one entity; and

            (ii) there shall not have occurred any downgrading, nor shall any
     notice have been given of any intended or potential downgrading or of any
     review for a possible change that does not indicate the direction of the
     possible change, in the rating accorded any securities of DigitalNet
     Holdings, the Company, or the Subsidiary Guarantor or any of their
     respective subsidiaries by any "nationally recognized statistical rating
     organization" as such term is defined for purposes of Rule 436 under the
     Securities Act.

     (c) OPINION OF COUNSEL FOR THE COMPANY. On the Closing Date the Initial

that:

            (i) for the period from and after the date of this Agreement and
     prior to the Closing Date there has not occurred any Material Adverse
     Change;

            (ii) the representations, warranties and covenants of it set forth
     in Section 1 of this Agreement are true and correct with the same force and
     effect as though expressly made on and as of the Closing Date; and

            (iii) it has complied with all the agreements and satisfied all the
     conditions on its part to be performed or satisfied at or prior to the
     Closing Date.

     (k) PAYMENT OF EXISTING CREDIT FACILITY. The Company shall have furnished

is terminated by the Initial Purchasers pursuant to Section 5, or if the sale to
the Initial Purchasers of the Securities on the Closing Date is not consummated

the Company or the Subsidiary Guarantor to perform

<Page>

any agreement herein or to comply with any provision hereof, DigitalNet
Holdings, the Company and the Subsidiary Guarantor jointly and severally agree
to reimburse the Initial Purchasers (or such Initial Purchasers as have

observe the following procedures in connection with the offer and sale of the
Securities:

     (A) Offers and sales of the Securities will be made only by the Initial

     AVAILABILITY OF THE EXEMPTION PROVIDED BY RULE 144 FOR RESALE OF THE

     Following the sale of the Securities by the Initial Purchasers to
Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall
not be liable or responsible to DigitalNet Holdings, the Company, the Subsidiary
Guarantor or their respective subsidiaries for any losses, damages or
liabilities suffered or incurred by DigitalNet Holdings, the Company, the
Subsidiary Guarantor or their respective subsidiaries, including any losses,
damages or liabilities under the Securities Act, arising from or relating to any
resale or transfer of any Security.

     SECTION 8. INDEMNIFICATION.

     (a) INDEMNIFICATION OF THE INITIAL PURCHASERS. DigitalNet Holdings, the
Company and the Subsidiary Guarantor jointly and severally agree to indemnify
and hold harmless each Initial Purchaser, its directors, officers and employees,
and each person, if any, who controls any Initial Purchaser within the meaning
of the Securities Act and the Exchange Act against any loss, claim, damage,
liability or expense, as incurred, to which such Initial Purchaser or such
controlling person may become subject, under the Securities Act, the Exchange
Act or other federal or state

<Page>

statutory law or regulation, or at common law or otherwise (including in
settlement of any litigation, if such settlement is effected with the written
consent of the Company), insofar as such loss, claim, damage, liability or
expense (or actions in respect thereof as contemplated below) arises out of or
is based: (i) upon any untrue statement or alleged untrue statement of a
material fact contained in the Preliminary Offering Memorandum or the Offering
Memorandum (or any amendment or supplement thereto), or the omission or alleged
omission therefrom of a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; or (ii) in whole or in part upon any inaccuracy in the
representations and warranties of DigitalNet Holdings, the Company or the
Subsidiary Guarantor contained herein; or (iii) in whole or in part upon any
failure of DigitalNet Holdings, the Company or the Subsidiary Guarantor to
perform its obligations hereunder or under law; or (iv) any act or failure to
act or any alleged act or failure to act by any Initial Purchaser in connection
with, or relating in any manner to, the offering contemplated hereby, and which
is included as part of or referred to in any loss, claim, damage, liability or
action arising out of or based upon any matter covered by clause (i) above,
provided that none of DigitalNet Holdings, the Company or the Subsidiary
Guarantor shall be liable under this clause (iv) to the extent that a court of
competent jurisdiction shall have determined by a final judgment that such loss,
claim, damage, liability or action resulted directly from any such acts or
failures to act undertaken or omitted to be taken by such Initial Purchaser
through its gross negligence or willful misconduct; and to reimburse each
Initial Purchaser and each such controlling person for any and all reasonable
expenses (including the fees and disbursements of counsel chosen by Banc of
America Securities LLC) as such expenses are reasonably incurred by such Initial
Purchaser or such controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action; provided, however, that the foregoing indemnity
agreement shall not apply to any loss, claim, damage, liability or expense to
the extent, but only to the extent, arising out of or based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the
Company by the Initial Purchasers expressly for use in any Preliminary Offering
Memorandum or the Offering Memorandum (or any amendment or supplement thereto).
The indemnity agreement set forth in this Section 8 shall be in addition to any
liabilities that DigitalNet Holdings, the Company or the Subsidiary Guarantor
may otherwise have.

     (b) INDEMNIFICATION OF DIGITALNET HOLDINGS, THE COMPANY, THE SUBSIDIARY
GUARANTOR AND THEIR RESPECTIVE DIRECTORS AND OFFICERS. Each Initial Purchaser
agrees, severally and not jointly, to indemnify and hold harmless DigitalNet
Holdings, the Company, the Subsidiary Guarantor and each of their respective
directors and each person, if any, who controls DigitalNet Holdings, the Company
or such Subsidiary Guarantor within the meaning of the Securities Act or the
Exchange Act, against any loss, claim, damage, liability or expense, as
incurred, to which DigitalNet Holdings, the Company, such Subsidiary Guarantor
or any such director, or controlling person may become subject, under the
Securities Act, the Exchange Act, or other federal or state statutory law or
regulation, or at common law or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of such
Initial Purchaser), insofar as such loss, claim, damage, liability or expense
(or actions in respect thereof as contemplated below) arises out of or is based
upon any untrue or alleged untrue statement of a material fact contained in any
Preliminary Offering Memorandum or the Offering Memorandum (or any amendment or
supplement thereto), or arises out of or is based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make

<Page>

the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Offering Memorandum or the
Offering Memorandum (or any amendment or supplement thereto), in reliance upon
and in conformity with written information furnished to the Company by the
Initial Purchasers expressly for use therein; and to reimburse DigitalNet
Holdings, the Company, such Subsidiary Guarantor or any such director or
controlling person for any legal and other expenses reasonably incurred by
DigitalNet Holdings, the Company, such Subsidiary Guarantor or any such director
or controlling person in connection with investigating, defending, settling,
compromising or paying any such loss, claim, damage, liability, expense or
action. DigitalNet Holdings, the Company and the Subsidiary Guarantor hereby
acknowledge that the only information that the Initial Purchasers have furnished
to the Company expressly for use in any Preliminary Offering Memorandum or the
Offering Memorandum (or any amendment or supplement thereto) are the statements
set forth as the eighth paragraph following the "Table of Contents" concerning
stabilization by the Initial Purchasers and in the third, fourth and fifth
paragraphs under the caption "Plan of Distribution" in the Offering Memorandum;
and the Initial Purchasers confirm that such statements are correct. The
indemnity agreement set forth in this Section 8 shall be in addition to any
liabilities that each Initial Purchaser may otherwise have.

     (c) NOTIFICATIONS AND OTHER INDEMNIFICATION PROCEDURES. Promptly after
receipt by an indemnified party under this Section 8 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 8, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 8 or to the extent it is not
materially prejudiced through the forfeiture of substantial rights or defenses
as a proximate result of such failure. In case any such action is brought
against any indemnified party and such indemnified party seeks or intends to
seek indemnity from an indemnifying party, the indemnifying party will be
entitled to participate in and, to the extent that it shall elect, jointly with
all other indemnifying parties similarly notified, by written notice delivered
to the indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel reasonably
satisfactory to such indemnified party; provided, however, if the defendants in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that a conflict may
arise between the positions of the indemnifying party and the indemnified party
in conducting the defense of any such action or that there may be legal defenses
available to it and/or other indemnified parties which are different from or
additional to those available to the indemnifying party, the indemnified party
or parties shall have the right to select separate counsel to assume such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Upon receipt of notice from the indemnifying
party to such indemnified party of such indemnifying party's election so to
assume the defense of such action and approval by the indemnified party of
counsel, the indemnifying party will not be liable to such indemnified party
under this Section 8 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel (together with local counsel), approved by the indemnifying
party

<Page>

(Banc of America Securities LLC in the case of Section 8 and Section 9),
representing the indemnified parties who are parties to such action) or (ii) the
indemnifying party shall not have employed counsel satisfactory to the
indemnified party to represent the indemnified party within a reasonable time
after notice of commencement of the action, in each of which cases the
reasonable fees and expenses of counsel shall be at the expense of the
indemnifying party.

     (d) SETTLEMENTS. The indemnifying party under this Section 8 shall not be
liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
against any loss, claim, damage, liability or expense by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by Section 8
hereof, the indemnifying party agrees that it shall be liable for any settlement
of any proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement, compromise or consent to the entry
of judgment in any pending or threatened action, suit or proceeding in respect
of which any indemnified party is or could have been a party and indemnity was
or could have been sought hereunder by such indemnified party, unless such
settlement, compromise or consent includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.

     SECTION 9. CONTRIBUTION. If the indemnification provided for in Section 8
is for any reason held to be unavailable to or otherwise insufficient to hold
harmless an indemnified party in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then (i) each indemnifying party
shall contribute to the aggregate amount paid or payable by such indemnified
party, as incurred, as a result of any losses, claims, damages, liabilities or
expenses referred to therein in such proportion as is appropriate to reflect the
relative benefits received by DigitalNet Holdings, the Company and the
Subsidiary Guarantor, on the one hand, and the Initial Purchasers, on the other
hand, from the offering of the Securities pursuant to this Agreement or (ii) if
the allocation provided by clause (i) above is not permitted by applicable law,
in such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of DigitalNet
Holdings, the Company and the Subsidiary Guarantor, on the one hand, and the
Initial Purchasers, on the other hand, in connection with the statements or
omissions or inaccuracies in the representations and warranties herein which
resulted in such losses, claims, damages, liabilities or expenses, as well as
any other relevant equitable considerations. The relative benefits received by
DigitalNet Holdings, the Company and the Subsidiary Guarantor, on the one hand,
and the Initial Purchasers, on the other hand, in connection with the offering
of the Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company, and the total discount received by the Initial Purchasers bear to
the aggregate initial offering price of the Securities. The relative fault of
DigitalNet Holdings, the Company and the Subsidiary Guarantor, on the one hand,
and the Initial Purchasers, on the other hand, shall be determined by reference
to, among other things, whether any such untrue or alleged untrue statement of a

<Page>

material fact or omission or alleged omission to state a material fact or any
such inaccurate or alleged inaccurate representation or warranty relates to
information supplied by DigitalNet Holdings, the Company and the Subsidiary
Guarantor, on the one hand, or the Initial Purchasers, on the other hand, and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

     The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities and expenses referred to above shall be deemed to include,
subject to the limitations set forth in Section 8, any legal or other fees or
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim. The provisions set forth in Section 8 with
respect to notice of commencement of any action shall apply if a claim for
contribution is to be made under this Section 9; provided, however, that no
additional notice shall be required with respect to any action for which notice
has been given under Section 8 for purposes of indemnification.

     DigitalNet Holdings, the Company, the Subsidiary Guarantor and the Initial
Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation (even if the
Initial Purchasers were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to in this Section 9.

     Notwithstanding the provisions of this Section 9, no Initial Purchaser
shall be required to contribute any amount in excess of the discount received by
such Initial Purchaser in connection with the Securities distributed by it. No
person guilty of fraudulent misrepresentation (within the meaning of Section 11
of the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Initial Purchasers'
obligations to contribute pursuant to this Section 9 are several, and not joint,
in proportion to their respective commitments as set forth opposite their names
in Schedule A. For purposes of this Section 9, each director, officer and
employee of an Initial Purchaser and each person, if any, who controls an
Initial Purchaser within the meaning of the Securities Act and the Exchange Act
shall have the same rights to contribution as such Initial Purchaser, and each
director of DigitalNet Holdings, the Company, or the Subsidiary Guarantor, and
each person, if any, who controls DigitalNet Holdings, the Company, or such
Subsidiary Guarantor or such subsidiary with the meaning of the Securities Act
and the Exchange Act shall have the same rights to contribution as DigitalNet
Holdings, the Company, or such Subsidiary Guarantor.

     SECTION 10. TERMINATION OF THIS AGREEMENT. Prior to the Closing Date, this
Agreement may be terminated by the Initial Purchasers by notice given to the
Company if at any time: (i) trading in securities generally on either the Nasdaq
Stock Market or the New York Stock Exchange shall have been suspended or
limited, or minimum or maximum prices shall have been generally established on
any of such stock exchanges by the Commission or the NASD; (ii) a general
banking moratorium shall have been declared by any of federal, New York,
Delaware or California authorities; (iii) there shall have occurred any outbreak
or escalation of national or international hostilities or any crisis or
calamity, or any change in the United States or international financial markets,
or any substantial change or development involving a prospective substantial
change in United States' or international political, financial or economic
conditions, as in the reasonable judgment of the Initial Purchasers is material
and adverse and makes it

<Page>

impracticable to market the Securities in the manner and on the terms described
in the Offering Memorandum or to enforce contracts for the sale of securities;
(iv) in the reasonable judgment of the Initial Purchasers there shall have
occurred any material adverse change, in the condition, financial or otherwise,
or in the earnings, business, operations or prospects, whether or not arising
from transactions in the ordinary course of business, of DigitalNet Holdings and
its subsidiaries, considered as one entity; or (v) DigitalNet Holdings, the
Company or the Subsidiary Guarantor shall have sustained a loss by strike, fire,
flood, earthquake, accident or other calamity of such character as in the
reasonable judgment of the Initial Purchasers may interfere materially with the
conduct of the business and operations of DigitalNet Holdings, the Company and
the Subsidiary Guarantor, taken as a whole, regardless of whether or not such
loss shall have been insured. Any termination pursuant to this Section 10 shall
be without liability on the part of (i) DigitalNet Holdings, the Company or the
Subsidiary Guarantor to any Initial Purchaser, except that DigitalNet Holdings,
the Company and the Subsidiary Guarantor shall be obligated to reimburse the
expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any
Initial Purchaser to DigitalNet Holdings, the Company and the Subsidiary
Guarantor, or (iii) any party hereto to any other party except that the
provisions of Section 8 and Section 9 shall at all times be effective and shall
survive such termination.

     SECTION 11. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY. The
respective indemnities, agreements, representations, warranties and other
statements of DigitalNet Holdings, the Company and the Subsidiary Guarantor, of
their respective officers and of the several Initial Purchasers set forth in or
made pursuant to this Agreement will remain in full force and effect, regardless
of any investigation made by or on behalf of any Initial Purchaser or DigitalNet
Holdings, the Company, the Subsidiary Guarantor or any of its or their partners,
officers or directors or any controlling person, as the case may be, and will
survive delivery of and payment for the Securities sold hereunder and any
termination of this Agreement.

binding upon the parties hereto, including any substitute Initial Purchasers
pursuant to Section 16 hereof, and to the benefit of the employees, officers and
directors and controlling persons referred to in Section 8 and Section 9, and in
each case their respective successors, and no other person will have any right
or obligation hereunder. The term "successors" shall not include any purchaser
of the Securities as such from any of the Initial Purchasers merely by reason of
such purchase.

     SECTION 14. PARTIAL UNENFORCEABILITY. The invalidity or unenforceability of
any Section, paragraph or provision of this Agreement shall not affect the
validity or enforceability of any other Section, paragraph or provision hereof.
If any Section, paragraph or provision of this Agreement is for any reason
determined to be invalid or unenforceable, there shall be deemed to be made such
minor changes (and only such minor changes) as are necessary to make it valid
and enforceable.

     SECTION 15. GOVERNING LAW PROVISIONS. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK
APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

     (a) CONSENT TO JURISDICTION. Any legal suit, action or proceeding arising
out of or based upon this Agreement or the transactions contemplated hereby
("Related Proceedings") may be instituted in the federal courts of the United
States of America located in the City and County of New York or the courts of
the State of New York in each case located in the City and County of New York
(collectively, the "Specified Courts"), and each party irrevocably submits to
the non-exclusive jurisdiction (except for proceedings instituted in regard to
the enforcement of a judgment of any such court (a "Related Judgment"), as to
which such jurisdiction is non-exclusive) of such courts in any such suit,
action or proceeding. Service of any process, summons, notice or document by
mail to such party's address set forth above shall be effective

<Page>

service of process for any suit, action or other proceeding brought in any such
court. The parties irrevocably and unconditionally waive any objection to the
laying of venue of any suit, action or other proceeding in the Specified Courts
and irrevocably and unconditionally waive and agree not to plead or claim in any
such court that any such suit, action or other proceeding brought in any such
court has been brought in an inconvenient forum. Each party not located in the
United States irrevocably appoints CT Corporation System, as its agent to
receive service of process or other legal summons for purposes of any such suit,
action or proceeding that may be instituted in any state or federal court in the
City and County of New York.

     SECTION 16. DEFAULT OF ONE OR MORE OF THE SEVERAL INITIAL PURCHASERS. If
any one or more of the several Initial Purchasers shall fail or refuse to
purchase Securities that it or they have agreed to purchase hereunder on the
Closing Date, and the aggregate number of Securities which such defaulting
Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase
does not exceed 10% of the aggregate number of the Securities to be purchased on
such date, the other Initial Purchasers shall be obligated, severally, in the
proportions that the number of Securities set forth opposite their respective
names on Schedule A bears to the aggregate number of Securities set forth
opposite the names of all such non-defaulting Initial Purchasers, or in such
other proportions as may be specified by the Initial Purchasers with the consent
of the non-defaulting Initial Purchasers, to purchase the Securities which such
defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused
to purchase on such date. If any one or more of the Initial Purchasers shall
fail or refuse to purchase Securities and the aggregate number of Securities
with respect to which such default occurs exceeds 10% of the aggregate number of
Securities to be purchased on the Closing Date, and arrangements satisfactory to
the Initial Purchasers and the Company for the purchase of such Securities are
not made within 48 hours after such default, this Agreement shall terminate
without liability of any party to any other party except that the provisions of
Section 4, Section 6, Section 8 and Section 9 shall at all times be effective
and shall survive such termination. In any such case either the Initial
Purchasers or the Company shall have the right to postpone the Closing Date, as
the case may be, but in no event for longer than seven days in order that the
required changes, if any, to the Offering Memorandum or any other documents or
arrangements may be effected.

     As used in this Agreement, the term "Initial Purchaser" shall be deemed to
include any person substituted for a defaulting Initial Purchaser under this
Section 16. Any action taken under this Section 16 shall not relieve any
defaulting Initial Purchaser from liability in respect of any default of such
Initial Purchaser under this Agreement.

     SECTION 17. GENERAL PROVISIONS. This Agreement constitutes the entire
agreement of the parties to this Agreement and supersedes all prior written or
oral and all contemporaneous oral agreements, understandings and negotiations
with respect to the subject matter hereof. This Agreement may be executed in two
or more counterparts, each one of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement may not be amended or modified unless in writing by all of the
parties hereto, and no condition herein (express or implied) may be waived
unless waived in writing by each party whom the condition is meant to benefit.
The section headings herein are for the convenience of the parties only and
shall not affect the construction or interpretation of this Agreement.
